Fig. 1From: MLAA-based attenuation correction of flexible hardware components in hybrid PET/MR imagingWorkflow of the xMLAA algorithm for estimation of hardware attenuation. Input data are the PET emission data and an initial attenuation map of the phantom/patient. The initial attenuation map does not include information on the attenuation of flexible hardware components. Activity and attenuation distributions are updated in an alternating manner. The attenuation update is only applied outside the patient outlineBack to article page
